In his own mind...NO! Many people can make themselves believe many things. But literally speaking he can know a man who is circumcised, just doesn't have the knowledge of it because he hasn't seen him nude, asked or been told that man was circed!
It was Abraham who had all the children of God be circumcised as a covenant to God. Abraham I beleive circed himself (ouch) at age 90 (double ouch!) and so all the Abrahamic religions and followers should be cut...but no! HA! We have the sinners for not following God's word. Of course out of the 3 Abrahamic religions (Judaism, Christianity and Islam), the only one that does not require circumcision is Christianity. Jews do it at 8 days old by a mohel...Moslems, it is not stated in the Koran but the Haddiths do say that Mohammed (Who was born perfect, in other words without foreskin, forget the term) said to his followers to circumcise the males in order to be hygenic...among other things as showers (Turkish baths anyone?) and shaving most of the body, especially the pubic area. These are seen in the Haddiths I beleive. Christians...well...in order to convert the European savages at the time who were scared the ritual they decided it was not necessary to do it. They also ruled out many other things such as eating meat from hooved animals, drinking alcohol to get drunk among other things. We can thank Peter the Apostle for this...who also changed Mary Magdalane to a Whore, by so making women worthless creatures, or just worth for obedience. The Bible was changed, modified and now we have the bastardized, and prostituted religion called Christianity and all it's offsprings from Orthodox Churches to the Protestants. I believe Coptic Christians in Egypt do require circumcision following the true Christian traditions...which were much or less very close to Judaism...but Europeans were too scared to do it. In order for mass conversion (Which meant more money for the CHURCH) we have what we have...people following a blind-faith...LOL!
Anyways....I've been to Britain...London especially I lived there for a year...visited the Fit Ladz place many times and was impressed to see how many circed Brits there were. yeah, few times got circed Americans, Aussies and Canadians, but local Brits told me they had it done for pleasure (Which I was very surprised about) seeing these young Londoners getting Circed! WOW! Hot: British, Cute, Young, and Circumcised= HOT! But by about 7/10, those were uncut...which was were I first tasted my uncuts...thank God they're a sea away from me! Went out with one of the circed guys I met there and it was great, he went goes to Imperial College in Westminster...where I was going also. So Circed Brits are not rare...upper classes tend to circ their children as well. I even heard that after Di's death, the Prince's both underwent the circ tradition. If only Princess Di knew about the new AIDS results in Africa among cut and uncut..she would be an advocate for circumcision....for God's sake, she was getting f*cked by 2...Prince Charles and that Egyptian guy she died with! She should know how good it is!
As an American who was circed at age 19....I can say I am very happy with my decision....only mad cause my parents didn't do me like it was custom at birth! My lil bros did get circed tho at birth. If I ever have sons, they will get circed as well. Be proud of your circ and 16 is not a young age to mak that decision....if you can already drive and drink in many countries, sure as Hell you can chose to get snipped for the better of you!
